The Altimetry of Electromagnetic Wave on the Observation Station of the Earth's Surface Subsidence of Diggings

随着全站仪测量系统的推广应用,我们采用电磁波测高代替四等几何水准测量方法获取地表移动变形的监测信息,应用于矿区地表移动变形规律的研究,介绍了电磁波测高代替四等几何水准测量的具体作业方法,通过理论推演对其达到的测量精度进行了分析;该方法的应用,使平面和高程观测同步进行,更加充分发挥全站仪三维同步观测的优越性;实践证明:该方法操作简单、自动化程度高、精度可靠,是一种值得推广的方法。

Along with the promotion and application of the measurement system of entire station meter, instead of the quarter - geometry leveling method, the altimetry by using electromagnetic wave has already been used to gain the monitor information about the surfaces migration and distortion. And its also applied to the research on the rules of the surface S migration and distortion in diggings. This paper introduces the idiographic methods of operation concerning how to usethe altimetry of electromagnetic wave to replace the quarter - geometry leveling. Also analyses the measuring accuracy through deducing some theories. The application of this method makes the observation of plane and elevation progressed synchronously. WhatS more, it fully displays the superiority of three - dimensional synchronized observation by using the entire station meter. Through the practice, it has proved that, advantages of this method are simple operation,high automatic degree, reliable precision. And it is worth popularizing.
